Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a heat radiation pipe is interposed between the heat source and the fluid, then the heat can be radiated to the fluid, but thermal conduction loss occurs and heat efficiency decreases
Solution Approach 1:
The patent replaces the conventional thermal conduction-based heating system with an electromagnetic induction heating system. The IH coil generates a magnetic field that directly induces eddy currents in the heat radiation pipe, converting electromagnetic energy into thermal energy without requiring thermal conduction through intermediate components. This substitution eliminates thermal conduction losses and reduces power consumption.
Solution Approach 2:
The patent utilizes the phase transition of electromagnetic energy to thermal energy through electromagnetic induction. The IH coil generates a time-varying magnetic field that induces eddy currents in the conductive heat radiation pipe, transforming electromagnetic energy into thermal energy directly within the pipe walls, thereby heating the fluid efficiently without thermal conduction losses.
2Object-affected harmful factors
If the IH coil is supported by the heat radiation pipe, then electric leakage is suppressed, but the coil may be affected by vibrations
Solution Approach 1:
The patent introduces a holder as an intermediary component between the IH coil and the heat radiation pipe. The holder provides electrical insulation to prevent electric leakage from the coil to the pipe, while also mechanically supporting the coil in a fixed position relative to the pipe. This intermediary structure isolates the coil from vibrations of the pipe while maintaining electrical safety.
Solution Approach 2:
The patent segments the support structure into distinct functional components: the holder that provides electrical insulation and positional support, and the heat radiation pipe that conducts heat. This segmentation allows the IH coil to be electrically isolated from the pipe while maintaining a stable spatial relationship, preventing both electric leakage and vibration-induced heating fluctuations.
